Definitions
- This invention relates to a coupling mechanism for a refrigerant compressor, and more particularly, to a mechanism for disconnecting the drive shaft of the compressor from a drive pulley in the event of a compressor malfunction.
- an electromagnetic clutch is interposed between the automotive engine and the drive shaft of the compressor to intermittently transmit the rotational driving force of the engine to the shaft.
- the operation of the electromagnetic clutch is controlled by a change in the operating conditions of the air conditioning system, for example, a change of temperature in the passenger compartment.
- the clutch In the event of a compressor malfunction, the clutch should operate to disconnect the engine from the compressor to prevent transmission of the rotational driving force from the engine.
- the clutch since the clutch is usually loaded in a compressor which has a variable displacement mechanism, which enable the compressor to change its capacity in direct response to changes in operating conditions, the electromagnetic clutch is not necessary to obtain satisfactory control of the refrigeration or temperature condition of the air conditioning system. Nevertheless, it is necessary to provide the compressor with a safety mechanism to prevent damage to other parts of the engine or air conditioning system in the event of a compressor malfunction.
- the electromagnetic clutch serves as an expensive solution to this problem.
- pulley 1 is directly connected to the outer terminal end of drive shaft 3 and extends around the outer peripheral surface of tubular extension 2 of drive shaft 3.
- the rotational driving force of the engine is constantly transmitted to drive shaft 3 through pulley 1 via a drive belt (not shown). Since pulley 1 is never disconnected from drive shaft 3 even in the event of a compressor malfunction, such a malfunction is directly passed on to the driving system of the automobile. Damage on the engine and other parts of the driving system is likely to occur.
- the driven member may be a compressor for an automotive air conditioner.
- a coupling mechanism for a driven member for example, a compressor, in accordance with the present invention includes a pulley which is rotatably and peripherally disposed on a surface of the drive shaft which is outside the main compressor housing.
- a circular plate-like element is fixed to the outer end of the drive shaft.
- a plurality of cylindrical members are disposed between the inner surface of the plate-like element and the outer surface of the pulley and couple the plate-like element to the pulley.
- the cylindrical members are made of materials which break easily if a predetermined torque is exceeded. This predetermined torque is exceeded if the operation of the compressor is interrupted preventing the rotation of the drive shaft. If the torque should be exceeded, the cylindrical members break and the connection between the pulley and the driven member or compressor is terminated and the pulley is allowed to rotate freely.
- FIG. 1 one is a cross sectional view of a conventional coupling mechanism used on a compressor.
- FIG. 2 is a cross sectional view of a coupling mechanism, used on a compressor, in accordance with one embodiment of this invention.
- FIG. 3a is a rear end view of a plate-element of the coupling mechanism shown in FIG. 2.
- FIG. 3b is a cross sectional view taken along line A--A of FIG. 3a.
- FIG. 4a is a rear end view of a modified plate-like element for a coupling mechanism in accordance with a second embodiment of this invention.
- FIG. 4b is a cross sectional view taken along line B--B of FIG. 4a.
- a coupling mechanism may be installed, for example, on a refrigerant compressor for a automobile air conditioning system.
- the compressor has compressor housing 10 and front end plate 11 attached to an open end thereof.
- Drive shaft 12 is rotatably supported within front end plate 11.
- Tubular extension 11 extends outwardly from front end plate 11 and surrounds drive shaft 12.
- Pulley 14 is rotatably supported on the peripheral outer surface of tubular extension 111 through bearing 15. Pulley 14 is securely fitted on the peripheral outer surface of bearing 15 by snap ring 16 disposed between an inner surface of pulley 14 and the inner end surface, with respect to housing 10, of bearing 15. Snap ring 16 prevents pulley 14 from moving in a direction parallel to the rotational axis of drive shaft 12. Bearing 15 is secured between flange 112 and snap ring 17 which is fixed on the peripheral outer surface of tubular extension 111.
- Circular plate-like element 13 have a centrally located hole is fixed on a terminal outer end portion of drive shaft 12 by a bolt and a nut. Plate-like element 13 is also coupled with drive shaft 12 by the interaction of key 20 on the end of shaft 12 with key groove 132 in the centrally located hole of plate-like element 13.
- a plurality of cylindrical members 18 are disposed between the inner side surface, with respect to housing 10, of plate-like element 13 and the outer side surface, also with respect to housing 10, of pulley 14 to couple plate-like element 13 to pulley 14. Holes 131 are formed on the inner side surface of plate-like element 13 and one end of each cylindrical member 18 is disposed therein. The other end of each cylindrical member 18 is disposed in corresponding hole 141 formed on the outer side surface of pulley 14.
- cylindrical members 19 are integrally formed with plate-like element 13.
- Cylindrical members 18 or 19 are made of synthetic resins or metals which are easily broken if a large torque acts between pulley 14 and plate-like element 13 that is, a force which acts to rotate pulley 14 with respect to plate-like element 13.
- Suitable materials for constructing cylindrical members 18 include polyamide, polycarbonate, polyacetal and other engineering plastics, as well as aluminum, iron, lead, bronze and other metals.
- cylindrical members 19 and plate-like element 13 are made of the same material which must be a metal.
- the driving force of the engine is transmitted to pulley 14 by a belt (not shown), and is then transferred to drive shaft 12 of a compressor through cylindrical members 18 and plate-like element 13. In this manner, drive shaft 12 is driven. If during the operation of the compressor a malfunction occurs, and as a result of the malfunction the rotation of drive shaft 12 is interrupted, the rotational movement of plate-like element 13 is also stopped due to the coupling of the plate-like element 13 with drive shaft 12. However, a large rotational force is still provided to pulley 14 by the engine and pulley 14 provides a large torque to plate-like element 13 through cylindrical members 18. This torque is large enough to destroy cylindrical members 18 because cylindrical members 18 are designed to break when such a torque is received.
- pulley 14 is disconnected from plate-like element 13 and is free to rotate without resistance from motionless drive shaft 12 applied through plate-like element 13.
- the exact value of the torque and thus the size, material and number of cylindrical members 18 or 19 is dependent on the system with which the coupling mechanism is used.
- cylindrical members 18 are destroyed and must be replaced, cylindrical members 18 are easy to replace and are inexpensive, especially when compared to the cost of an electromagnetic clutch or the cost of repairing damage to the engine. Although in the second embodiment plate-like element 13 must be entirely replaced if broken, the cost of replacement is still much less than the above mentioned clutch or repairs.
